TPM350 Thermally Conductive Phase Change Material Product Description TPM350 is a high-performance screen printable thermally conductive phase change material, which rated at a thermal conductivity of 3.5W/m-K. The phase change temperature is 50C. TPM350 contains a solvent to allow for wetting of the surface, and assist in processing. Moreover, the product will dry to the touch after the solvent evaporates, so it will eliminate the mess associated with grease. Features Screen printable Thermal conductivity: 3.5W/m-K Minimizes contact thermal resistance Lower phase change temperature:50C Contain solvent, excellent wet ability Approvals RoHS Compliant Yes Typical Applications High frequency microprocessors Notebook and desktop PCs Computer servers DC/DC converters Memory modules Cache chips IGBTs Automotive Optical Typical Properties Colour: Grey 3 2.2g/cm Density: 50 Phase Change Temperature: -40~+125C Operation Temperature Range: 3.5 W/m-K Thermal Conductivity: Thermal Resistance 70C, 50psi: 0.026 C-in/W Minimum Bond Line Thickness: 25m Storage Store between 5C and 35C and below 50% relative humidity, upright away from corrosive materials. Keep lid tightly closed when not in use. Keep jar and jar lip clean to ensure a tight seal. Directions for use Mix well by hand or jar roller before using. High shear mixing will result in accelerated solvent evaporation and high viscosities. Ensure the surface of the substrate is clean prior to application using an approved cleaning solvent (Toluene, Acetone, or IPA). A uniform coating 0.002-inches (0.05mm) to 0.010-inches (0.25mm) thick should be used. For high volume applications stenciling or screening is recommended. When screening, best results are achieved with a 61 (or less) threads per inch (TPI) screen, however the phase change has been successfully applied using up to a 140 mesh screen. (The higher the number = smaller screen opening). Material surface is dry to the touch within 2 hours at 60C or 10 hours at room temperature varying upon the environment. Suggest to remove the solvent away completely at 60C especially for the application with thickness higher than 0.1mm. Solvent evaporation does not affect the thermal performance of TPM350, but may result in difficulties during application.
